Measurement Canada and the regulation of thermal energy meters

Regulation is coming to the Canadian thermal metering market.

Measurement Canada is moving forward with industry regulations and meter type approval. QMC is applying to Measurement Canada to participate in the pilot program including the provision of initial inspection service of thermal meters. This builds upon our expertise with the electrical metering inspection program and installation verification services.

thermal energy meter installations:

  1. Clients should be installing thermal energy meters which meet the EN-1434, OILM R75 and CAN/CSA-C900.1-13 standards, these documents are the basis of the Measurement Canada specification.
  2. Product approvals to start in 2018, all unapproved devices to be removed by 2026.  New developers would not want to order meters now that do not meet the standards above as they will have to remove the meters well before their end of life.

what you need to know from MEASUREMENT CANADA:

There are currently no specific requirements for thermal energy meters within the Weights and Measures Act and Regulations. While thermal energy meters are not exempt from the requirement to be approved and inspected prior to use in trade, Measurement Canada has not previously evaluated these devices. The proposed requirements and program for the regulation of thermal energy meters would provide a framework for Measurement Canada to approve and inspect these devices.

Measurement Canada sought trade sector input in 2010 which formed the basis of the current proposal to regulate thermal energy meters.  The review generated these recommendations found on Measurement Canada’s site page, Consultation on thermal energy meters:

  • require type approval of all thermal energy meters used in trade
  • require initial inspection of all thermal energy meters used in trade
  • require mandatory periodic inspections of all thermal energy meters used in trade
  • exempt measuring devices used in the steam subsector from approval and inspection
  • harmonize requirements with international standards, where appropriate
  • develop alternative service delivery programs to have authorized service providers perform initial inspections and mandatory periodic inspections (if required)
